Guidelines for Law Enforcement

These guidelines are intended for law enforcement authorities seeking information about Medium accounts or users. These guidelines are intended to help inform law enforcement and the public about our practices, and are not legal advice. Requests may only be submitted via mail to our mailing address, listed below. 


What is Medium?

Medium is an online publishing platform that lets users read, write, and share ideas and information. People and organizations publish content through our website, mobile site, and client applications. You can learn more at our about page.


What Account or User Information Does Medium Have?

Most Medium information is public. Please see our Privacy Policy for more information on the data we collect from or about users.

Medium provides hosting for written content, account profile photos and header photos, as well as some image uploads. However, users may also post images that are not hosted by Medium (for example, by embedding a photo or video from another site).


Data Retention Practices

Medium retains different types of non-public information for different time periods. For example, our server logs are retained for a maximum of 9 months. More information on Medium’s retention policies can be found in our Privacy Policy.

Account holders are able to deactivate and delete their accounts. Content deleted by account holders is generally not retained or available.


Requests for Medium Account Information

Medium responds to valid legal process seeking user account information issued in compliance with U.S. law.

Requests may only be submitted by mail to our mailing address. 

Requests must be made on law enforcement letterhead. 

You may also send a courtesy notification of the request via email to, but we do not accept legal process solely via email.

What Details Must Be Included in Account Information Requests?

When requesting user account information, please include:

  • The @username and URL of the subject Medium account in question (e.g., @Medium and
    Please see this article about Medium accounts and URL structures. 
  • Details about the specific information requested (e.g., basic subscriber information) and its relationship to your investigation;
  • A valid official email address (e.g., so we may get back in touch with you upon receipt of your legal process.
  • A signature and name of the requesting official;

Please ensure that the information you seek is not publicly available on our site. We are unable to process overly broad or vague requests.



Preservation Requests

If we receive a valid request from U.S. law enforcement to preserve records which constitute potentially relevant evidence in legal proceedings, we will preserve, but not disclose, a temporary snapshot of the relevant account records for 90 days pending service of valid legal process.

Preservation requests, in accordance with applicable law, should:

  1. Be signed by the requesting official;
  2. Include the @username and URL of the subject Medium profile (e.g., @Medium and;
  3. Have a valid return official email address; and
  4. Be sent on law enforcement letterhead.


Subpoena or Court Order

Non-public, non-content information about Medium users will be released to law enforcement only in response to appropriate legal process such as a subpoena, court order, or other valid legal process — or in response to a valid emergency request, as described below.

Search Warrant

Contents of communications (e.g., post drafts and photos) will be released only in response to a valid search warrant from an agency with proper jurisdiction over Medium.


Mutual Legal Assistance Treaties

A Mutual Legal Assistance Treaty (MLAT) defines how the U.S. and another country will help each other in legal matters such as criminal investigations. Through an MLAT, a foreign government can ask the U.S. government for help in obtaining evidence from entities in the U.S., including companies like Medium. If the U.S. government approves the request, Medium would respond to it.

Medium’s policy is to promptly respond to requests that are issued via U.S. court either by way of a MLAT or letters rogatory upon proper service of process.


Medium Will Notify Users of Requests for Account Information Unless Prohibited from Doing So

Medium’s policy is to notify users of requests for their account information and provide a copy of the request prior to disclosure unless we are prohibited from doing so (e.g., we receive an order under 18 U.S.C. § 2705(b)).

Exceptions to prior notice may include exigent or counterproductive circumstances (e.g., emergencies or account compromises).

In cases in which we are not permitted to give a user prior notice, we will provide post-disclosure notice to the user unless legally prohibited from doing so.


Production of Records and Records Authentication

Unless otherwise agreed prior to disclosure, we currently provide responsive records in electronic format.

The records that we produce are self-authenticating. Additionally, the records are electronically signed to ensure their integrity at the time of production. If you require a declaration, please explicitly note that in your request.

Emergency Disclosure Requests and Exigent Circumstances

In line with our Privacy Policy, we may disclose account information to law enforcement in response to a valid emergency disclosure request. Under 18 U.S.C. §§ 2702(b)(7) and 2702(c)(4), Medium is permitted — but under no obligation — to voluntarily disclose information, including contents of communications and customer records, to a federal, state, or local governmental entity if Medium believes in good faith that an emergency involving imminent danger of death or serious physical injury to any person requires such disclosure without delay.

Medium evaluates emergency disclosure requests on a case-by-case basis in compliance with relevant U.S. law (e.g., 18 U.S.C. § 2702(b)(8)). If we receive information that gives us a good faith belief that there is an exigent emergency involving the danger of death or serious physical injury to a person, we may provide information necessary to prevent that harm, if we have it.

How To Make an Emergency Disclosure Request

If there is an exigent emergency that involves the danger of death or serious physical injury to a person that Medium may have information necessary to prevent, law enforcement officers can submit an emergency disclosure request by mail or by email to with subject “Emergency Disclosure Request” (the quickest and most efficient method).

Please include all of the following information in an emergency disclosure request:

  • Clear indication on your cover sheet, which must be on law enforcement letterhead, that you’re submitting an Emergency Disclosure Request;
  • Identity of the person who is in danger of death or serious physical injury;
  • The nature of the emergency (e.g., report of suicide, bomb threat);
  • Medium @username and URL (e.g., @Medium and of the subject account(s) whose information is necessary to prevent the emergency;
  • Any specific posts you would like us to review;
  • The specific information requested and why that information is necessary to prevent the emergency;
  • The signature of the submitting law enforcement officer; and
  • All other available details or context regarding the particular circumstances.

International law enforcement authorities may also submit requests for emergency disclosure.
